MELTING TOT.

Application filed October 25, 1920. Serial No.

T 0 all whom it may concern:

Be it known that 1, JOHN B. MoCLAm, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Melting Pot, of which the following is a full, clear, and exact description.

This invention relates to melting pots or bowls and is especially designed for reducing or melting aluminum, Babbitt metal,

' co-pending application, Serial No. 403,703.

A further object in view is to provide a pot or bowl which includes a removable nozzle, whereby the same may be detached to permit of the application or removal of the bowl from the furnace.

With the above recited and other objects in view the invention consists in the novel construction, combination and arrangement of parts, set forth in the following description, pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a vertical sectional view through the bowl illustrating the application of the same to a furnace.

Figure 2 is a transverse sectional view through the furnace taken approximately on the line 22 of Figure 1 and illustrating the bowl in plan view.

Figure 3 is a similar view taken approximately on the line 3-3 of Figure 1.

Referring to the drawings by characters of reference, 10 designates a fragmentary portion of the shell or body of the furnace which is lined with fire brick or any other suitable refractory material 11. A fragmentary portion of a drum or cylindrical fender 12 is supported'by and extends up- Specification of Letters ratent.

in one side thereof which is covered by the swinging doors 14:.

The melting pot 15 is preferably constructed of semi-steel and is of parabolical formation with the bottom thereof materially thicker than the side walls, in order to resist the action of the heat from the fire box whereby to prevent destruction of the bowl and add to the life of the same. When the bowl becomes heated, the ma terial of which it is constructed will absorb and maintain the heat for a long period of time. In order .to provide means for drawlng 0d the molten metal from the bowl, without the necessity of ladling the same, the bottom of the bowl is provided with an integral laterally extending spout 16 having an opening 17 therethrough which communicates with the interior of thebowl as at l8 and provides a valve seat with which the lower extremity 19 of the shaft 20 co-acts. The shaft 20 is threaded as at 21 and the threaded portion thereof is received in the threaded bore 22 of the integral bracket 23 which extends inwardly from the outer edge of the bowl above the spout .16. The outer free end of the spout 16 terminates in alignment with the upper side edge of the bowl and the upper and outer peripheral edge of the bowl is provided with a flange 24 which is designed to rest upon the fire brick 11 for supporting the bowl within the furnace. The outer end of the bore 17 is interiorly threaded as at 25 for the reception of the threaded end of the spout or nozzle 26 which is designed to be inserted through the opening 27 in the side of the furnace. By thisarrangement it is obvious that upon the detachment of the nozzle from the spout, the same may be lifted from the furnace or inserted the-rein at will. The upper extremity of the shaft 20 is provided with a manipulating hand wheel 28 and access may be had to said wheel through the opening 13 for seating or unseating the extremity 19 from its seat to effect the drawing ofi of the molten metal from the bowl. The spout 16 will be constantly heated from the fire box at all times to prevent clogging of the bore 17 thereof.

While there has been shown and described a single and preferred embodiment of the invention, it is understood that. he right is reserved to others than those actually illustrated herein, to the fullest extent indicated by the general meaning of the terms in which the claims are expressed and by variations in the phraseology of the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

, 1. The combination with a furnace having upper and lower compartments, the latter of reduced cross sectional dimension to provide a horizontal shoulder, said lower com partment having an opening in one of its side walls, of a melting pot of parabolical formation having an outwardly extending peripheral flange at its upper end adapted to engage said shoulder for supporting the melting pot within the lower compartment, a downwardly and laterally directed integral spout extending from the bottom of said melting pot and affording a space thereabove for the free circulation of heat thereabout for heating the outlet nozzle on all sides and allowing the portion of the bowl lying above the outlet nozzle to be subjected to the heat, said nozzle being provided with a central bore communicating with the interior of the melting pot and having its outer end in vertical alignment with the side of the pot and with itsbore disposed in a horizontal plane with the opening in the side wall, a detachable nozzle adapted to be received by the outer end of the spout and insertable through the opening in the side Wall of the furnace, and means located within the bowl for closing the inner end of the bore of the nozzle having a manipulating device extending above the bowl for actuating the closure.

2. A melting pot for use in connection with furnaces of the character described, comprising a bowl of parabolical formation having an outwardly extending peripheral flange at its upper end and a downwardly and outwardly directed outlet nozzle at its lower end affording a space thereabove for the free circulation and action of the heat on all sides of the outlet nozzle and the pol'- tion of the bowl lying above the same, the outer end of said outlet nozzle being dis posed in vertical alignment with the upper and outer periphery of the bowl, an inwardly projecting integral bearing bracket extending horizontally from the inner and upper portion of-the bowl having a vertical threaded aperture therein, a threaded stem mounted therein provided with a conical lower extremity adapted to coact with the bore of the outlet nozzle for respectively closing and opening the same upon vertical movements thereof, and a detachable spout insertable through the furnace wall and engageable within the bore of the nozzle at its outer end.
